ABSTRACT
OBJECTIVE To understand the effects of meropenem on the biofilms of Pseudomonas aeruginosa lasR/rhlR mutations in vitro.METHODS The biofilms of PAEO1 and its lasR,rhlR,and lasR rhlR mutants were incubated in a polyvinyl chloride tube in 0.9% saline for three days,then were immersed in meropenem solution of 26 ?g/ml for 24 hours,and examined by scanning electron microscopy(SEM).RESULTS After three days incubation,PAEO1 biofilms showed a well-developed structure,however,the biofilms of PAEO1 lasR,rhlR,and lasR rhlR mutants were thin and poor developed;after 24 hours in meropenem solution,PAEO1 biofilm become rareness,whereas PAEO1 lasR,rhlR,and lasR rhlR mutants biofilms were almost destructed and only small pieces left.CONCLUSIONS lasR/rhlR Genes play probably an important role in the formation of P.aeruginosa biofilm and in the resistance to meropenem.
